So I was thinking, that I could sell my modded PS2 for this (I know where to get one for $400-$500). Only problem is, that because it only plays Japanese PS2 games, and Swap Magic obviously wouldn't work on this, is there any modchip that would work on this? Or any version of HDLoader/HDAdvance (since it has a 250GB hard drive)?

EDIT: I'd also like to point out, that calling any version of the Playstation 1 a "PSX" is incorrect, as this is the official "PSX", and the only reason people call is "PSX" is because at the time, PS1 was supposed to (eXperimentally) be able to play SNES games, but Nintendo didn't allow it and ended up just playing PS1 games.
